So I have a new project I work which I move in a room (panoramic picture). Now I want to open something on mouseClick. But when I try even to print something to the console in the mouseClick event it doesn't work.

g.drawImage(s, locationX,locationY,img.getIconWidth(),img.getIconHeight(), null);
}

I have a problem with connecting screenshots in the report generated by allure using jenkins.
1. I have an interface called ListenersT

public void onTestStart(ITestResult arg0) {

public void onTestSuccess(ITestResult arg0) {
// TODO Auto-generated method stub
}
}
I have screenshot support attached here
In each test, the listener "#Listeners ({ListenersT.class})" has been added to the beginning.
#Listeners({ListenersT.class})
Still, I don't see screenshots in the generated report
Please help.
I am trying to implment CompletableFuture which invokes a dummy callback method when completed.
However, after adding CompletableFuture.get() method my main class doesn't terminate.
I tried replacing CompletableFuture.get() with Thread.sleep(5000) but it doesn't seem to be right approach.
Please suggest what is causing CompletableFuture.get() to keep blocking even if the thread is complete.
import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ExecutionException;
import java.util.stream.IntStream;
public class CallableAsyncWithCallBack {
public static void main(String[] args) throws InterruptedException {
CompletableFuture<String> compFuture=new CompletableFuture<String>();
compFuture.supplyAsync(()->{
//Compute total
long count=IntStream.range(Integer.MIN_VALUE, Integer.MAX_VALUE).count();
return ""+count;
}).thenApply(retVal->{
try {
return new CallBackAsynchClass(retVal).toString();
} catch (InterruptedException | ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "";
}
);
System.out.println("Main Thread 1");
try {
compFuture.get();
} catch (ExecutionException e) {
e.printStackTrace();
}
System.out.println("Lock cleared");
}
}
class CallBackAsynchClass
{
String returnVal="";
public CallBackAsynchClass(String ret) throws InterruptedException, ExecutionException {
System.out.println("Callback invoked:"+ret);
returnVal=ret;
}
#Override
public String toString() {
return "CallBackAsynchClass [returnVal=" + returnVal + "]";
}
}
I am expecting "Lock cleared" to be outputted but .get() seems to be holding up the lock.
.thenApply function returns a new instance of CompletableFuture, and it's this instance that you need to use, try using this way instead :
public class CallableAsyncWithCallBack {
public static void main(String[] args) throws InterruptedException {
CompletableFuture<String> compFuture = CompletableFuture.supplyAsync(() -> {
//Compute total
long count = IntStream.range(Integer.MIN_VALUE, Integer.MAX_VALUE).count();
return "" + count;
});
CompletableFuture<String> future = compFuture.thenApply(retVal -> {
try {
return new CallBackAsynchClass(retVal).toString();
} catch (InterruptedException | ExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ""; });
System.out.println("Main Thread 1");
try {
future.get();
} catch (ExecutionException e) {
e.printStackTrace();
}
System.out.println("Lock cleared");
}
}
Hope this helps
How can I create a Spring Aspect (annotation driven e.g. #ExceptionTranslation) surrounding an entire method and put this method in a try...catch method?
#ExceptionTranslation
public void method() {
// do some stuff here...
}
so logically it does:
public void method() {
try {
// do some stuff here ...
} catch( Exception ex ) {
}
}
Below you can find a sample implementation of AfterThrows advice solving your problem.

I have written the following code, as I was trying to understand the situation where I would use ThreadLocals:-
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
public class TestDF {
private DateFormat df = new SimpleDateFormat("MM/dd/yy");
public String formatCurrentDate() {
System.out.println(">>>>>>>"+Thread.currentThread().getName());
Date d = new Date();
return df.format(d);
}
public String formatFirstOfJanyary1970() {
System.out.println(">>>>>>>" + Thread.currentThread().getName());
Date d = new Date(0);
return df.format(d);
}
public static void main(String[] args) {
TestDF df = new TestDF();
Thread t1 = new Thread(new WorkerThread(df));
Thread t2 = new Thread(new WorkerThread1(df));
t1.start();
t2.start();
}
public static class WorkerThread implements Runnable {
TestDF df;
public WorkerThread(TestDF df) {
this.df = df;
}
#Override
public void run() {
Thread.currentThread().setName("Worker-Thread 1");
System.out.println("Inside Thread1*");
System.out.println("Thread 1 "+df.formatCurrentDate());
System.out.println("Inside Thread1**");
try {
Thread.sleep(5000l);
System.out.println("Inside Thread1***");
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public static class WorkerThread1 implements Runnable {
TestDF df;
public WorkerThread1(TestDF df) {
this.df = df;
}
#Override
public void run() {
Thread.currentThread().setName("Worker-Thread 2");
System.out.println("Inside Thread2*");
System.out.println("Thread 2 "+df.formatFirstOfJanyary1970());
System.out.println("Inside Thread2**");
try {
Thread.sleep(5000l);
System.out.println("Inside Thread2***");
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
The out which I am receiving is as follows:-
Inside Thread1*
Inside Thread2*
>>>>>>>Worker-Thread 2
>>>>>>>Worker-Thread 1
Thread 1 06/09/15 <--
Thread 2 06/09/15 <--
Inside Thread1**
Inside Thread2**
Inside Thread1***
Inside Thread2***
I am aware that SimpleDateFormat is not thread-safe; but still couldn't make out how is happening.
When I use Windows to run eclipse Android emulator to connect socket,it was successful.
However, when I use Mac os lion to run the "Same" code ,the emulator shows"unfortunately

If I understand correctly, you are executing MyServer on your machine, where you also run the emulator. If the Activity running in the emulator wants to establish a connection with MyServer, then it should use the following IP address : 10.0.2.2 (and not localhost, which references the emualor loopback interface).
